Zafgen Reports Fourth Quarter and Full Year 2019 Financial Results

Zafgen and Chondrial Therapeutics previously announced a definitive merger agreement

Merger creates clinical-stage company focused on the development of novel protein replacement therapies for rare diseases

Transaction expected to close in the second quarter of 2020

BOSTON, March 05, 2020 (GLOBE NEWSWIRE) -- Zafgen, Inc. ZFGN today reported its fourth quarter and full year 2019 financial results.

In December 2019, Zafgen and Chondrial Therapeutics, Inc., announced that the two companies had entered into a definitive merger agreement. Under the merger agreement, Chondrial Therapeutics will become a wholly-owned subsidiary of Zafgen, and the stockholders of Chondrial Therapeutics will become the majority owners of Zafgen's outstanding common stock upon the close of the merger. The proposed merger will result in a combined publicly traded, clinical-stage biopharmaceutical company operating under a new name, Larimar Therapeutics, Inc. The transaction is expected to close in the second quarter of 2020, subject to approvals by stockholders of each company and other customary closing conditions.

Chondrial Therapeutics' lead asset, CTI-1601, is in Phase 1 clinical development for the treatment of Friedreich's ataxia (FA), a progressive and irreversible mitochondrial disease caused by a genetic defect resulting in abnormally low amounts of frataxin. FA typically presents in childhood or adolescence and leads to devastating symptoms and early death. The company believes there are approximately 15,000 patients in the U.S. and E.U. Currently, there are no cures and no therapies that can modify the course of the disease. CTI-1601 has received Rare Pediatric Disease Designation and Fast Track Designation from the U.S. Food and Drug Administration. Topline results from the Phase 1 clinical program are expected by the end of 2020.

Fourth Quarter and Full Year 2019 Financial Results

Cash, Cash Equivalents and Marketable Securities

As of December 31, 2019, the Company had cash, cash equivalents and marketable securities totaling $70.3 million.

Net Loss

The Company reported a net loss for the fourth quarter of 2019 of $7.3 million, or $0.19 per share, compared to a net loss of $14.6 million, or $0.39 per share, for the fourth quarter of 2018. The net loss for the fourth quarter of 2019 includes $1.5 million of restructuring charges. For the full year 2019, the Company reported a net loss of $45.4 million, or $1.22 per share, compared to $61.4 million, or $1.90 per share, for the full year 2018. The net loss for the full year 2019 includes $5.6 million of restructuring charges.

The weighted average common shares (basic and diluted) outstanding used to compute net loss per share were 37.4 million for the fourth quarter of 2019 compared to 37.0 million for the same quarter of 2018. For the full year 2019, weighted average common shares (basic and diluted) outstanding used to compute net loss per share were 37.3 million compared to 32.2 million for the full year 2018.

Research and Development Expenses

Research and development expenses for the fourth quarter of 2019 were $0.4 million compared to $11.5 million for the fourth quarter of 2018. The decrease in research and development expenses compared to the prior year period was primarily due to the discontinuation of the MetAP2 program. Research and development expenses in the fourth quarter of 2019 consist of wind-down costs associated with closing out the MetAP2 program.

For the full year 2019, research and development expenses were $23.9 million, compared to $47.9 million for the full year 2018. The decrease in research and development expenses for the full year period was primarily due to the decision to discontinue the MetAP2 program during the third quarter of 2019.

Restructuring Charges

Restructuring charges for the fourth quarter and full year 2019 were $1.5 million and $5.6 million, respectively, and include personnel related costs primarily related to severance expenses as a result of the multiple reductions in workforce and contract termination costs implemented during 2019.

General and Administrative Expenses

General and administrative expenses for the fourth quarter of 2019 were $5.3 million, compared to $3.2 million for the fourth quarter of 2018. The increase in general and administrative expenses as compared to the prior year period was primarily due to an increase in professional fees related to strategic alternative activities and an increase in personnel related costs following the signing of the definitive merger agreement.

For the full year 2019, general and administrative expenses were $16.2 million, compared to $13.2 million for the full year 2018. The increase in general and administrative expenses for the full year 2019 as compared to the prior year period was primarily due to an increase in professional fees related to strategic alternative activities and an increase in personnel related costs following the signing of the definitive merger agreement.
